This is surgery to replace a damaged heart valve. The heart's four valves open and tightly close. The tricuspid and mitral valves allow blood to flow from one chamber to another. The pulmonary and aortic valves allow blood to flow to the large blood vessels. The valves make it so that blood can only flow forward when the heart squeezes. Usually, only one valve is replaced at a time. However, at times, one or more valves may need to be replaced. The new heart valves can be:
Mechanical, made of metal and plastic, such as a St. Jude valve
Made of tissue—most commonly from a pig or a cow, but they may also be supplied by a human donor or even made from your own tissue
—a test that uses sound waves to visualize functioning of the heart, including the valves
—a test that uses radiation to take a picture of structures inside the body
—a test that records the electrical activity of the heart
—the insertion of a tube-like instrument into the heart through an artery to detect problems with the heart and its blood supply. It can also accurately define the valve problem.
Leading up to your procedure:
Talk to your doctor about your medications. You may be asked to stop taking some medications up to one week before the procedure.
Arrange for a ride to and from the hospital.
Arrange for help at home after the surgery.
Eat a light meal the night before the surgery. Do not eat or drink anything after midnight.
will be used. It will block any pain and keep you asleep through the surgery. It is given through an IV.
The doctor will cut through the skin and breastbone. The chest cavity will be opened. Next, your heart will be connected to a heart-lung machine. This machine will take over the functions of the heart and lungs during the surgery. Next, the heart will be stopped. An incision will be made and the damaged valve will be removed. The new valve will be stitched into place. The doctor will check to make sure the valve opens and closes properly. The incision in the heart will be closed, and the heart will be restarted. After the heart is working fine, you will be removed from the heart-lung machine. The chest will be closed with wires. Lastly, the skin will be closed with sutures.
While you are recovering at the hospital, you may be instructed to:
Breathe deeply and cough 10-20 times every hour to help keep your lungs working well.
Walk with assistance. You may be encouraged to walk 2-3 days after surgery.
Take blood thinners to prevent blood clots from forming around the valve. If you have a tissue valve, you will not need a blood thinner. If you have a mechanical valve, you will have to take the medication for the rest of your life.
To help with your recovery, you may need to:
Take medications to control pain or prevent blood clots.
